A Moreton wave, Solar Tsunami, or Moreton-Ramsey wave is the chromospheric signature of a large-scale solar corona shock wave. Described as a kind of solar "tsunami", [1] they are generated by solar flares. They are named for American astronomer Gail Moreton, an observer at the Lockheed Solar Observatory in Burbank, and Harry E. Ramsey, an ...
Intense solar storms may also be hazardous to high-latitude, high-altitude aviation [7] and to human spaceflight. [8] Geomagnetic storms are the cause of aurora. [9] The most significant known solar storm, across the most parameters, occurred in September 1859 and is known as the "Carrington event". [10]
Other forms of solar activity frequently associated with coronal mass ejections are eruptive prominences, coronal dimming, coronal waves and Moreton waves, also called solar tsunami. Magnetic reconnection is responsible for CME and solar flares. Magnetic reconnection is the name given to the rearrangement of magnetic field lines when two ...
The TARDIS is caught in the first waves of a "solar tsunami" and materialises on Earth in the 22nd century.The Eleventh Doctor, Amy and Rory find themselves on a remote island, where a factory housed in a former 13th century castle monastery pumps a valuable, highly corrosive acid to the mainland.
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
The March 1989 geomagnetic storm occurred as part of severe to extreme solar storms during early to mid March 1989, the most notable being a geomagnetic storm that struck Earth on March 13. This geomagnetic storm caused a nine-hour outage of Hydro-Québec's electricity transmission system .
The town of Merak was destroyed by a tsunami that was 46 metres high. [note 2] The waves reached heights of up to 24 metres (79 feet) along the south coast of Sumatra and up to 42 metres (138 feet) along the west coast of Java. [15] The tsunamis washed the land clean of vegetation and destroyed human settlements. [13]
